One thing that has bugged me about my R100S is that I could not see the blue high beam indicator light, and the other instrument lights were "adequate", but just barely.
I just knew there had to be a fix for this... and KATDASH was the answer.
Very well engineered high quality product, detailed installation instructions, only took one hour to install.
I highly recommend KATDASH to every loyal Airhead owner.

I have seen numerous positive customer reviews of the KATDASH circuit board for the speedo-tach unit. It indeed looks to be a superior product.

However, if all you needed was brighter indicator lamps, then adding new #194 and #74 LED bulbs to the instrument cluster would accomplish the same for about $350 cheaper. I have the 1979 "green face" gauges, and so as suggested here several years ago, I replaced the illumination bulbs in all 4 gauges with green LEDs. I replaced the Hi Beam indicator with a blue LED, etc, etc.

www.superbrightleds.com/cat/miniature-we.../Base_Type,74,1,4023 :

I ride during the day with my Hi Beam ON, so it is important to me to be able to see this indicator in bright sun light. The LED indicator bulbs accomplish this task quite nicely. I can see this indicator at noon, even through sun glasses.

The only bulb that should not be converted to LED is the Alternator warning lamp. This since the resistance of the incandescent bulb figures prominently in the system charging rates.


Obviously, if your gauge pack circuit board has been molested by fools over the last 40 years, then you may only have the option of full circuit board replacement. In those cases the KATDASH is the obvious choice. However, if your circuit board is in good condition and you ONLY want a few brighter indicators, then discrete LEDs is an option to consider. I'm not saying either choice is right or wrong. Surely each case must to be considered on a very individual basis.

Hope this helps.
